erosion is when sediment is moved by wind, water, ice, and gravity.
which of the following are examples of erosion?
a dust storm passes through an area experiencing a drought.
rushing water carries soil away from the bank, making a river wider.
a rock cracks as it expands in the intense heat during the day.
limestone dissolves as it comes in contact with acid rain.
a glacier picks up a boulder as it moves across the bedrock.

Explanation:

To determine examples of erosion (sediment moved by wind, water, ice, gravity):

• A dust storm passes...: Wind moves dust (sediment) → erosion.
• Rushing water carries...: Water moves soil (sediment) → erosion.
• A rock cracks...: Thermal expansion (weathering, not erosion).
• Limestone dissolves...: Chemical weathering (not erosion).
• A glacier picks up...: Ice (glacier) moves a boulder (sediment) → erosion.

Answer:

A. A dust storm passes through an area experiencing a drought.
B. Rushing water carries soil away from the bank, making a river wider.
E. A glacier picks up a boulder as it moves across the bedrock.
